High Quality Content by WIKIPEDIA articles! A wedding ring or wedding band consists of a metal ring. Depending on the local culture, it is worn on the base of the right or the left ring finger. Such a ring symbolizes marriage: a spouse wears it to indicate a marital commitment to fidelity. The European custom of wearing such a ring has spread widely beyond Europe. According to some customs, the wedding ring forms the last in a series of gifts, which also may include the engagement ring, traditionally given as a betrothal present. This tradition was already in use in Ancient Rome and is possibly much older. Other more recent traditions, encouraged by the jewelry trade, seek to expand the idea of a series of ring-gifts with the pre-engagement ring, often given when serious courting begins, and the eternity ring, which symbolizes the renewal or ongoing nature of a lasting marriage, sometimes given after the birth of a first child; and a trilogy ring, usually displaying three brilliant-cut round diamonds each, in turn, representing the past, present and future of a relationship.
